Unlike many units, this battery charger continuously charges at maximum current, tapering off only near full battery voltage. In this unit, the full load current of the supply transformer/rectifier ...

A simple method of charging a battery from a higher voltage battery is shown in the circuit below to the left. Only one resistor is needed to set the desired charging current and is calculated by ...

I designed a compact, standalone Li-ion battery charger that is simple to build, extremely affordable, and easy to integrate directly into projects.

The importance of proper battery charging. Two main schemes for battery charging. How to design a CCCV battery charger. Test results from the CCCV-based design. Battery-powered electronic devices have ...

Nerd Ralph loves cheap and dirty hacks, and for that we applaud him. His latest endeavor is a LiFePO4 battery charger that he made out of parts he had on hand for under $0.50 US. (Although we think he ...
